Ken Griffin is on a real-estate spending spree that’s seen him break a major record in the first weeks of 2019.

Most recently, he dished out $238 million for a sprawling New York City apartment. The 23,000-square-foot penthouse unit at 220 Central Park South is now the most expensive home ever sold in the US; it shattered the previous record, a $137 million Hamptons home purchased by Barry Rosenstein in 2014, by more than $100 million.

Just days before news of his NYC purchase was announced, news broke of Griffin’s $122 million mansion purchase in London. According to Bloomberg, the historic mansion is about a half mile from Buckingham Palace. And, on January 11, the Chicago Tribune reported that he dropped $58.75 million on 4 top-level floors in a Near North condominium in Chicago.

Here’s a quick look at some of Griffin’s notable properties, in the US and beyond.

Ken Griffin is a hedge-fund manager whose net worth is an estimated $8.84 billion. That makes him the richest man in Illinois and one of the richest men in the world.

Griffin is the CEO of Citadel, a hedge fund founded in 1990 that manages $30 billion in assets. He’s also well-known for his philanthropy — in August, for example, he donated $20 million to Norton Museum of Art in West Palm Beach, Florida — but currently, it’s his real-estate investments that are making the news.

The building is still under construction …

… and is separated from the southern entrance to Central Park by just one street.

Just days prior to his NYC purchase, news also broke of Griffin purchasing a $122 million London mansion at 3 Carlton Gardens. The Wall Street Journal reports that the purchase is one of the most expensive London has ever seen.

Griffin’s 200-year-old London pad overlooks St. James Park and includes a gym, a pool, and an underground extension.

Griffin also holds the record for the Chicago area’s priciest real-estate sale: According to the Chicago Tribune, in November 2018, he bought four floors of luxury condo building No. 9 Walton for $58.75 million.

The building has been described as Chicago’s “number one address” and is about a block away from the Waldorf Astoria.

Griffin also holds the real-estate record in Miami: In 2015, he dropped $60 million on two properties — a five-bedroom penthouse and the three-bedroom condo directly below it — in an 18-story condo called Faena House in Miami Beach.
